What it detects

This rule detects creation of ransom note files named with the DarkAngels Linux ransomware pattern where each encrypted file gets a paired README_TO_RESTORE note. It is associated with the DarkAngels Linux ransomware observed in development by Uptycs. Attackers drop these notes across encrypted directories to extort victims, and their presence indicates active data-encryption impact.
